Definitions
- the invention relates to a method for producing fiber-reinforced plastic parts in a mold. It also relates to an adhesive layer for carrying out the method.
- the wall thickness should preferably be designed to be as constant as possible from a structural point of view over the entire surface of the plastic part.
- the wall thickening which is disadvantageous in terms of casting, it is preferable to cast in tear-resistant fibers as reinforcement in order to improve the dimensional accuracy of the end product and reduce production costs.
- Handling the fibers is made easier by bundling them as a preliminary product in a separate machine and molding them with plastic to form a flexible band.
- This fiber-reinforced plastic tape is then fixed in the correct position in segments in the mold.
- the tape is covered with the liquid plastic on all of its surfaces facing into the mold, so that it is cast into the molded part and is integrated smoothly within its wall.
- DE 100 12378 C2 describes that a plastic tape reinforced with carbon fibers is unwound from a roll in the desired length and the first end that has become free is positioned in the desired position within the injection mold by a robot arm , is pressed against the injection mold by a pressure roller and then cut off.
- An electrical high-voltage generator is connected to the second end of the cast and electrically conductive carbon fiber.
- the other pole of the high voltage generator is connected to the electrically conductive injection mold.
- the high electrical voltage difference in the kilovolt range between the injection mold and the carbon fiber-reinforced plastic tape charges the plastic of the tape electrostatically, causing it to adhere to the surface of the injection mold.
- This approach has the disadvantage that electrically conductive fibers or an electrically conductive polymer are required for the tape. Electrically non-conductive fibers or plastics cannot be used.
- Another disadvantage is the complex electrical insulation of essential assemblies of the robot from its other components.
- Another disadvantage is the required electrical insulation of the surface of the injection mold, for which this expensive component has to be coated very laboriously. In particular for small series and individual items, the method according to DE 100 12378 C2 can only be used with unreasonably high effort.
- double-sided adhesive tapes are known from the current state of the art, which consist of an adhesive layer on a carrier film. They are unrolled - usually from a roll - and then applied to the desired location by applying pressure to the carrier film. In a second step, the carrier film is then peeled off from the adhesive layer.
- the main disadvantage of this procedure is the considerable effort in terms of working time and devices when introducing the adhesive layer and the carrier film, when removing the carrier film before injection molding and when removing the adhesive layer after casting.
- the invention has set itself the task of limiting the aforementioned disadvantages and for plastic parts that are to be produced in a mold, in particular by injection molding, extrusion or thermoforming, and partially reinforced in their mechanical strength by cast fibers to develop a universally applicable process that saves working time and material costs, is suitable for new as well as for existing systems and in which segments of fiber-reinforced plastic tapes as semi-finished products adhere flatly to the inner wall of the mold in the correct position, whereby this adhesion is so resilient, that it does not change or changes only slightly during the casting process and that the plastic tape adheres to the liquid plastic.
- this object is achieved in that the adhesive force of the adhesive layer on the mold is greater than the adhesive force of the adhesive layer on the segment, so that the adhesive layer remains completely in the mold after a first segment has been lifted off and after the temperature of the adhesive layer has increased through the Contact with a molten plastic matrix, the remaining adhesive force of the adhesive layer is sufficient for the adherence of at least a second segment.
- the adhesive layer is applied to the surface of the mold. If the adhesive does not bond with the introduced plastic at all, but only with the plastic of the segments of the flexible tape made of fiber-plastic composite material, then it can also be applied outside of the areas of the mold to be covered with the segments, e.g. by spraying or spraying . In this case, the adhesive does not chemically contaminate the workpiece. If the adhesive layer is only a few micrometers thick, then the geometry of the surface of the workpiece is not significantly affected in practice. But if the injected plastic reacts chemically with the adhesive layer, then the adhesive and the plastic must remain separate from each other.
- the advantages of the method according to the invention include that - in contrast to the electrostatic fixing of the segments - the limit values of 25 ⁇ m for the surface roughness and 1 mm per 10 cm for the waviness, which should not be exceeded during electrostatic attachment, when fixing by means of an adhesive layer can be exceeded.
- the segment separates the adhesive layer from the plastic introduced into the mold.
- the marginal tiny contact on the side walls of the adhesive layer will be negligibly small in many practical applications.
- a further development of the invention is that the associated adhesive layer is on a carrier film before it is introduced into the mold, the adhesive force of the adhesive layer on this carrier film being so low that the carrier film can be used as a mechanical carrier for the adhesive layer during the introduction , but is then peeled off the adhesive layer and the adhesive layer remains at least for the most part in the mold.
- the adhesive layer can be applied to a carrier film in exactly the same shape as the segment and pressed onto the exact point on the mold to which the segments are then to be glued. If the flattening force of the adhesive layer on the carrier film is less than that on the mold, the carrier film can be removed and disposed of or reused after it has been inserted and pressed on. The adhesive layer then remains alone on the surface of the mold. It should be noted that the subsequent insertion of the segments must be relatively very precise so that no part of the adhesive layer reacts with the injected plastic.
- the associated adhesive layer is already on the segment before it is introduced into the mold.
- a segment is provided with an adhesive layer before it is inserted.
- this adhesive layer can be covered with a protective film as transport protection, which must be removed before sticking.
- this first segment is poured into liquid plastic and removed from the mold with the finished molded part, the adhesive layer remains in the mold according to the invention. If a next one, then the next but one and many more segments in a row are glued to this adhesive layer, they must they are positioned quite precisely if the adhesive layer is always to be completely covered by the segment.
- the required positioning accuracy can be reduced by the fact that the adhesive layer covers only part of the area of the segment. It should be noted that the respective adhesive force must then still be sufficient.
- the adhesive layer when the adhesive layer is at a distance from the edge of the segment, the front of the gush of liquid plastic that flows into the mold will no longer lift the edge region of the segment lying directly on the mold. As a result, the liquid plastic does not slide between the segment and the mold and therefore does not come into contact with the adhesive layer.
- the adhesive strength of the adhesive layer decreases with each further use. If the segments can no longer be held and / or are displaced during injection, the old adhesive layer must either be covered with a fresh second adhesive layer, provided that the resulting double layer meets the requirements or the aged adhesive layer must be removed.
- chemical treatment, burning, peeling, scraping, melting and wiping or suction can be used, or a tape to which the adhesive adheres better than to the mold.
- a cleaning compound e.g. plastic
- the adhesive layer must build up an adhesive force to the cleaning compound that is higher than the adhesive force between the adhesive layer and the mold. Then the cleaning compound is removed from the mold as a whole together with the adhesive.
- the adhesive layer for carrying out the method according to the invention, the adhesive layer comprising two adhesive layers different adhesive force exists, wherein the adhesive layer facing the segment has a lower adhesive force than the adhesive layer facing the mold.
- the adhesive layers are selected from the group of polymerization, polyaddition and polycondensation adhesives, solvent-based adhesives, dispersion adhesives, hot melt adhesives, contact adhesives and plastisols, and preferably from the group of permanently tacky hot melt adhesives.
- a separating film is arranged between the two adhesive layers, which enables the two adhesive layers to be separated.
- Segments with a thickness of up to 5 mm perpendicular to the mold are preferably incorporated.
- the belt segments can be warped and / or curved to such an extent that the size of the remaining contact surfaces with the shape still ensures sufficient adhesive force.
- An improved integration into the plastic part is supported by a bevel on the edge of 10 to 70 ° or a radius on the edge.
- Figure 1 shows a section of an injection mold with glued therein
- FIG. 2 shows a curved segment with an adhesive layer and protective film
- FIG. 1 the corner part of an injection mold 2 is shown as a perspective detail, which serves to position a - dashed - drawn molded part F.
- This molded part F is provided at the corner shown with a short, horizontally and to the left extending support column F1, which is formed in the cavity 21 of the injection mold 2.
- the concavely curved transition from the trough 21 to the rear wall of the injection mold 2 is shown in FIG. 1 by hatching.
- the support column F1 If forces act on the end of the support column F1 shown on the far left, which are aligned transversely to the longitudinal axis, the support column F1 is particularly stressed at its transition points to the remaining area of the molded part F. In order to avoid tearing of the plastic material in this critical connection zone of the support column F1 with the rest of the molded part F, five segments 1 of a flexible band made of fiber-plastic composite material are cast in in this exemplary embodiment.
- the two segments 1 to be seen on the left are graphically cut, so that the fibers running therein approximately in the longitudinal direction of segment 1 are visible become.
- the respective adhesive layers 3, which fix the two segments 1 on the inner surface of the injection mold 2, are also cut in the drawing.
- FIG. 1 it is easy to understand that, before the molding of the molded part F, the segments 1 have to be fixed to the inner surface of the injection mold 2 with sufficient flattening force.
- the flattening force must not only be sufficient for the segments 1 to remain in the required position with the required accuracy, but also to adhere to the surface of the injection mold 2 as large as possible, especially in curved areas, so that they can cope with the surge from the wave of the injected liquid Resist plastic for the molded part F.
- adhesive layers 3 secure the flattening of the segments 1 on the injection mold 2. They are shown in FIG. 1 with a very large material thickness so that they can be recognized. In practice, however, they will only be a film that is so thin that it can hardly be seen as a separate layer, i.e. it does not leave a notch in the surface of the molded part F either.
- Both adhesive layers 3 consist of permanently tacky hot-melt adhesives with different adhesive strengths, the adhesive layer facing segment 1 having a lower adhesive strength than the adhesive layer facing the injection mold 2.
- the former is, for example, an adhesive layer based on thermoplastic rubber, while the latter is an adhesive made from synthetic rubber.
- the configuration of the material of the adhesive layers required for this is state-of-the-art based on catalogs and technical data from the adhesive manufacturer, depending on the materials of the injection mold, the plastic of the fiber-reinforced segment and taking into account the selected maximum temperature for the processing process.
- FIG. 1 shows the segments 1 can be fixed just as well on flat parts of the injection mold 2 as on curved parts.
- the flexible segments 1 can also be arranged in a rotated manner.
- larger reinforcements of the molded part F can be formed.
- FIG. 2 shows the state shortly before the segment 1 is introduced into the injection mold 2, in which the protective film 4 is started to be peeled off.
- a matrix made of polypropylene with a material thickness of 0.2 mm was introduced into an injection mold made of tool steel with a synthetic rubber coating on the surface as an adhesive layer.
- the flattening force between the adhesive layer and the surface of the injection mold was 1.4 times greater than the flattening force between the adhesive layer and the segment.
- the adhesive layer remained completely in the injection mold.
- the flattening force between the adhesive layer and the injection mold then decreased, but was still a factor of 1.2 greater than the flattening force between the adhesive layer and the next segment glued into the injection mold.
- the adhesive strength of the adhesive layer was no longer sufficient to glue another segment into the mold and to hold it there during the injection molding process. The adhesive layer then had to be removed from the mold.
- F molded part is reinforced by pouring segments 1 into the injection mold 2 F1 support column on molded part F.
